我购买了Ebay的廉价“最连接点”和STM32f013C8T6。 利用Windows 8的环礁和MCU的SWD接口,我能够上载和操作代码,设置突破点和观察变量,但我可以“在ITM或SWV追踪上使用印刷机”。
我也尝试采用真正的ST-LINK v2, 即Nucleo m32l152re委员会,结果相同。
ST-LINK和MCU之间的联系如下:
ST-LINK - MCU:
SWDIO - SWDIO, GND - GND, SWCLK - SWCLK, 3.3V - 3.3V
Unused pins on the ebay ST-LINK: RST, SWIM
Unused pins on the genuine ST-LINK: NRST, SWO
如果需要,我将乐于提供更多信息。
阅读。 必须在硬件一级修改共同廉价的ST-Link贴身,以暴露国际自动取款机追踪所依赖的SWO pin。 (当然,你还必须抓住这一信号)。
I ve got two different ST-Link clones, both of which connect nothing to the PA10 pin, like in the linked article.
我理解这个问题是老的。 我希望你们找到了解决办法,但我仍然想把两点放在一边,因为我遇到了同样的问题。
我的理解是,对于SWV功能而言,你需要连接SWO的钥匙。 当你有这一问题时,你能够看到例外的痕迹,或除印本外的任何SWV特征?
鉴于这一认识,我正在修改我的硬件,以支持今后使用的SWO的钥匙。
I assume you have already done what Atollic says in this link? Basically, ITM require the following things to redirect printf()
The application should send printf() output to an ITM channel
亲爱的JTAG必须支持SWV
变迁者必须拥有与相应的自动取款机渠道进行SWV追踪。
尽管你的供应商,但我假定所有的ST-Links都应支持印刷版的重新定位。 (其他,使用ST-Link 效用并更新STLink公司软件)
希望这一帮助。
我今天也面临同样的问题。 I m 采用STLink V2 clone, 后者有SWO(SWV) pin,我发现两种解决办法:
